## Checking plan

Verify time actually spent. AI arithmetic is checked independently. Proportionality is a lawyer call.

- What the AI does: Turn the time entries into a draft bill grouped by task, with entries that sit outside the disclosed scope flagged.
- What the lawyer does: Set the scope, verify the evidence, resolve exceptions and approve the final output for its intended use.
- Basis: Suggested checking approach based on the task guidance. Complete the assessment for the actual tool, information and jurisdiction.

## Checks the lawyer makes

1. Confirm the output against the client’s instructions and the complete relevant source material, including omissions or contradictions.
2. Verify every relied-on citation, figure and name against the source document.
3. The responsible lawyer approves the exact version before use.
